<br />Consulting Services Agreement between City of San Leandro and <br />Gates & Associates, Inc for Staff Augmentation Exhibit A – Page 8 of 31 <br />mitigation options. Once a feasible mitigation option has been verbally agreed upon by the City <br />and the applicable regulatory agencies, CONSULTANT will prepare a second memorandum <br />outlining the mitigation concept in a manner that can be incorporated into permit applications. <br />Subtask 2.10 —Sedimentation Testing at Boat Launch <br />Previous testing of lagoon and perimeter sediments where work is planned to occur indicate that <br />the material was suitable for a combination of Unconfined Aquatic Disposal and placement at <br />the Dredged Material disposal ponds near the Golf Course. Although minimal to no dredging is <br />proposed within the marina berth areas, the new Boat Launch area will require dredging of <br />materials that have not been dredged before. Sampling and testing, consistent with guidance <br />from the Dredged Material Management Office (DMMO), will be needed for the proposed <br />dredging and disposal of excavated material. Specific tasks associated with this include Pacific <br />EcoRisk performing the following: <br />● Preparation of the Sampling and Analysis plan (SAP) to be submitted to DMMO for <br />approval of the sampling program <br />● Sediment sampling based on DMMO requirements (4 sediment cores, one composite <br />sample tested) <br />● Laboratory analysis based on typical DMMO requirements <br />● Preparation of the Sediment Test Results (STR) to be submitted to DMMO <br />● Participation in meetings with DMMO <br /> <br />DELIVERABLES: <br />All deliverables shall be pdf format except as noted below. <br />● Bathymetric Survey <br />● Existing document summary <br />● Environmental Data Request List <br />● Geotechnical Report <br />● Hazardous Materials Abatement Specifications <br />● Hazardous Materials Report <br />● Memorandum of known compensatory mitigation options <br />● Memorandum summarizing project’s compensatory mitigation approach to be proposed <br />in permit applications <br />● One draft and one final Arborist Report <br />● One draft and one final Biological Resources Technical Memorandum <br />● Phase I Environmental Site Assessment <br />● Phase II Environmental Site Assessment to assess the former UST location and to <br />supplement previous sampling activities (increase spatial coverage of sample locations, <br />include limited soil vapor assessment) <br />● Project Issues and Constraint Summary <br />● Sediment Sampling and Analysis Plan <br />● Sediment Testing Results <br />● Supplemental Topographic Survey in AutoCad and pdf <br /> <br />DocuSign Envelope ID: 30A47DAA-8ADC-4C81-A393-00F3D4407ED9
